Title: Heterojunction bipolar transistor
Inventor: ONAKA SEIJI
IPC: H01L29/205
Filed: 1987-07-10
Abstract: PURPOSE:To reduce the contact resistance of an emitter and to perform a high speed operation in a heterojunction bipolar transistor by forming a base contact layer having a wider band gap than that of a base layer on the surface of a collector layer so as to be brought into contact with the base layer. CONSTITUTION:A one conductivity type reverse mesa-shaped emitter layer 5 having a wider band gap than that of a base layer is formed on the other conductivity type base layer 4 having narrower band gap than that of a collector layer partly provided on one conductivity type collector layer 3. Further, a base contact layer 7 having wider band gap than that of the layer 4 is so formed on the layer 3 as to be in contact with the base layer. Thus, the width of the layer 5 is narrowed and the width of an emitter electrode 8 can be widened. Accordingly, the collecting resistance of the emitter can be reduced to accelerate its operating speed.

Title: Coder and decoder
Inventor: YONEDA MINORU
IPC: H04N13/00
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To restore at least a reference image. SOLUTION: A discrimination section 51 discriminates an image selected as a reference image and changes an image selected for the reference image at a prescribed time interval. Based on the discrimination result, coding sections C1, C2,... are controlled so that they conduct coding using only the reference image or they code a difference from the reference image. Outputs from the coding sections C1, C2,... are outputted as independent coded streams. Since the coding streams used to transmit the reference image are changed at a prescribed time interval, even when any coding stream is impossible of transmission, for example, the reference image can almost be restored.
